Here are the last two maps, as well as various changes to the first four, adding in boss and miniboss names and correcting the stage names. I used every available source to be as accurate as possible considering that most sites seem to contradict each other.
The stage names are from the English manual and are, sadly, more generic than those I was using previously. They're official at least, and most likely accurate translations from the Japanese manual from what little I've been able to figure out using an online translator. Ditto for the names of the bosses aside from using "Death" instead of "Grim Reaper" since the later sounds more like a description than a name. As for the minibosses, they're only named in the Japanese manual but only one (Flying Wolf) was really puzzling and its name seems to have been translated accurately oo.
Now, before I actually submit these to the site, I'd really like some feedback. I've never added so much text information on any map I've done before these so I'm a bit nervous that I might have made typos or grammar mistakes. Or worse, that people just don't like having so many text boxes on their screenshot maps. So please, be honest!
